A couple questions

Postby fatesalign » Fri Aug 07, 2015 4:31 pm

First, I was wondering if you can buy a printer that has dead pixels? I'm assuming it's okay because the light still hits it, it's just not colored.

Second, how big of a build area can I get with a DLP that's 2200 lumens and 1024 x 768 (I believe that's what it was) while still having good quality?

Thanks for any answers!

To get an idea of resolution just divide the area by the resolution. A 1024x768 projector can print an area 10.24mm x 7.68mm at .1mm XY resolution

Sorry was late and I put the decimal place in the wrong spot. 102.4 x76.8

Why do people say you can't make it as big with a top down?

So to get up to about an 8 inch by 8 inch build, I'd have to spend hundreds on a 1080p projector?
